An economical and reliable system for the contained transfer of particulates by means of a series of transfer containers (140) facilitates the particulate transfer without either exposure of the operating personnel and the environment to the particulate, or environmental contamination of the particulate itself. The system employs a multiple o-ring canister assembly (110) which can be attached to either the discharging port (120) or charging port (135) of a piece of processing equipment. The canister has a series of circumferential o-ring grooves (115) which allows the attachment of a series of individual containers. In a charging mode, once the particulate is charged to the processing equipment, a first transfer container is collapsed and a second transfer container is placed in the next o-ring groove, thereby containing the remaining contaminated section (149) of the first transfer container. The first transfer container is removed through a bag-out sleeve (143) which is an integral part of the second transfer container. The process is repeated in a stepwise fashion by moving to the next groove in the canister until the process equipment is completely charged in a particulate contained manner.

Un système économique et fiable de transfert contenu de particules au moyen d'une série de conteneurs (140) de transfert facilite le transfert de particules évitant soit l'exposition du personnel d'exploitation et de l'environnement aux particules, soit la contamination de l'environnement par les particules elles-mêmes. Le système utilise un ensemble bidon (110) à joints toriques multiples pouvant être fixé soit à l'orifice de décharge (120) soit à l'orifice de charge (135) d'un élément de matériel de traitement. Le bidon présente une série de rainures circonférentielles (115) à joints toriques permettant la fixation d'une série de conteneurs individuels. Dans un mode de charge, une fois les particules chargées dans le matériel de traitement, un premier conteneur de transfert est comprimé et un second conteneur de transfert est placé dans la rainure à joint torique suivante, contenant ainsi la partie contaminée restante (149) du premier conteneur de transfert. Le premier conteneur de transfert est retiré par un manchon (143) à renflement lequel fait partie intégrante du second conteneur de transfert. Le procédé est répété par étapes par déplacement de la rainure suivante dans le bidon jusqu'à ce que le matériel de traitement soit complètement chargé d'une manière contenant les particules.
